BACKGROUND The GuideLiner catheter extension device is a monorail-type "Child" support catheter that facilitates coaxial alignment with the guide catheter and provides an appropriate back-up force. This device has been developed in the field of coronary intervention, and now is becoming widely applied in the field of endovascular treatment. However, there has been no report on the effectiveness of the guide catheter extension device in percutaneous transluminal renal angioplasty (PTRA). CASE REPORT We encountered a case of atherosclerotic subtotal occlusion at the ostium of the left renal artery...

OBJECTIVE: Outcomes from carotid artery stenting (CAS) are related to experience and technical expertise of the operator. Simulation of CAS may enhance clinical proficiency. We interrogated the impact of endovascular simulation of CAS procedures in operators who are at various stages of training. METHODS: Twelve trainees (students [n = 4]; junior surgery residents, postgraduate year [PGY] 1-3 [n = 4]; and senior surgery residents or fellows, PGY 4-7 [n = 4]) were apprised of characteristics of an endovascular simulator and CAS procedures...

Metallic zinc implanted into the abdominal aorta of rats out to 6 months has been demonstrated to degrade while avoiding responses commonly associated with the restenosis of vascular implants. However, major questions remain regarding whether a zinc implant would ultimately passivate through the production of stable corrosion products or via a cell mediated fibrous encapsulation process that prevents the diffusion of critical reactants and products at the metal surface. Here, we have conducted clinically relevant long term in vivo studies in order to characterize late stage zinc implant biocorrosion behavior and products to address these critical questions...

Historically, coronary artery bypass graft (CABG) surgery has been the standard revascularization method for unprotected left main coronary artery (LMCA) disease. Over the last decade, several randomized controlled trials (RCTs) have shown favorable results for percutaneous coronary intervention (PCI) with drug-eluting stent (DES) compared with CABG; however, no RCT has been conducted directly comparing DESs with medical therapy alone (MTA). Furthermore, the 2 most recently reported larger RCTs, using new-generation DESs reached somewhat conflicting conclusions comparing the 2 revascularization strategies...

Drug eluting devices have greatly evolved during past years to become fundamental products of great marketing importance in the biomedical field. There is currently a large diversity of highly specialized devices for specific applications, making the development of these devices an exciting field of research. The replacement of the former bare metal devices by devices loaded with drugs allowed the sustained and controlled release of drugs, to achieve the desired local therapeutic concentration of drug. The newer devices have been "engineered" with surfaces containing micro- and nanoscale features in a well-controlled manner, that have shown to significantly affect cellular and subcellular function of various biological systems...

Co-Cr-W-Ni alloy (L605) with high tensile strength is used in coronary stents. The thickness of individual strut of the stent is reduced which can decrease the stent restenosis rate. However, about 10% Ni element content in L605 is found to cause allergic reactions and pulmonary embolism, similar to the traditional 316L stainless steel. In this study, a novel nickel-free cobalt-base alloy Co-20Cr-12Fe-18Mn-2Mo-4W-N (wt%) was designed and fabricated in order to efficiently avoid the potential hazards of Ni element...

Zn and Zn-based alloys have been recognized as highly promising biodegradable materials for orthopedic implants and cardiovascular stents, due to their proved biocompatibility and, more importantly, lower corrosion rates compared to Mg alloys. However, pure Zn has poor mechanical properties. In this study, Ag is used as a promising alloying element to improve the mechanical properties of the Zn matrix as well as its biocompatibility and antibacterial properties. Accordingly, we design three ZnAg alloys with Ag content ranging from 2...

The most frequent ureteral lesions are iatrogenic, mainly due to gynecologic and urologic procedures. The resolution and repair of these lesions, when they require surgery, is often the performance of ureteroneocystostomy. We describe the technique for the repair of distal ureter lesions that preserves both anatomy and function of the urinary tract (1). The operation consists in dissection and extraction of the distal ureteral stump from its intramural tract to get at least 1 cm of free ureter, percutaneous insertion of a ureteral stent, checking the absence of tension between proximal ureter and distal dissected stump, end to end anastomosis and reinsertion of the distal ureter in the previously dissected bladder muscle layer...

Objective To evaluate the clinical safety and effectiveness of percutaneous rheolytic thrombectomy in patients with acute lower extremity deep venous thrombosis. Method Sixty-eight consecutive patients with acute massive lower extremity deep venous thrombosis were included in this retrospective study. A percutaneous rheolytic thrombectomy device (Angiojet ® Rheolytic thrombectomy catheter, Boston Scientific, Marlborough, MA, USA) was used in all patients in an angiography suite through ipsilateral popliteal vein access...

Objectives Various configurations of kissing stent (KS) configurations exist and patency rates vary. In response the covered endovascular reconstruction of the aortic bifurcation configuration was designed to minimize mismatch and improve outcome. The aim of the current study is to compare geometrical mismatch of kissing stent with the covered endovascular reconstruction of the aortic bifurcation configuration in vivo. Methods Post-operative computed tomographic data and patient demographics from 11 covered endovascular reconstruction of the aortic bifurcation and 11 matched kissing stent patients were included...

The dual microcatheter technique is an alternative treatment for stent-assisted coiling in acutely ruptured wide-necked aneurysms because of no antiplatelet therapy. We assessed the safety and efficacy of this technique in ruptured wide-necked aneurysms. Between March 2008 and March 2016, 56 acutely ruptured aneurysms were treated with the dual microcatheter technique. The angiographic results, treatment-related complications, and clinical outcome were documented. Angiographic follow-up was available in 37 patients at a mean of 20...

Eagle syndrome is defined by an elongated styloid process or a calcified stylohyoid ligament that impinges on surrounding structures and causes a variety of symptoms. Classically, Eagle syndrome presents as neck, throat, or ear pain. The vascular variant, stylocarotid syndrome, can present as headache, transient ischemic attack, or stroke. Carotid artery dissection is a rare complication of stylocarotid syndrome. We report a case of stylocarotid syndrome in a 60-year-old man who presented with a right internal carotid artery (ICA) dissection and focal neurological deficits...

Interventional radiology (IR) has become an integral part in the management of traumatic injuries. There is an ever-increasing role of IR in traumatic injuries of solid abdominal organs, pelvic and peripheral arteries to control active bleeding by therapeutic embolization or vascular reconstruction using stent grafts. Traditionally, these endovascular treatments have been offered to hemodynamically stable patients. However, in recent times endovascular approach has become preferable to surgery even in hemodynamically unstable patients with injury of surgically difficult-to-access sites...

OBJECTIVES: We sought to characterize how the perceived risk of early dual antiplatelet therapy (DAPT) discontinuation is incorporated into operator decision-making regarding stent choice, using a simple pre-procedure survey screening for clinical variables that may lead to early DAPT discontinuation. BACKGROUND: Understanding which factors influence operator decision-making regarding stent choice during percutaneous coronary intervention (PCI) could help identify areas for quality improvement...

OBJECTIVES: This study analyzed the outcomes of patients who presented with non-ST-elevation myocardial infarction (NSTEMI) and subsequently underwent orbital atherectomy for severe coronary artery calcification (CAC). BACKGROUND: Patients who present with NSTEMI have increased risk for death and recurrent MI after percutaneous coronary intervention (PCI). Patients with severe CAC have worse outcomes after PCI.Orbital atherectomy modifies calcified plaque, facilitating stent delivery and optimizing stent expansion...
